When CodecSys version 1.3 came out I gave it a try and liked the speed you get, just sucks that you're quite limited concerning cropping and stuff, even multiple passes is disabled for the PS3 version.

So I did take a look at it. I usually hate .Net but in this case it made things a lot easier and by a lot I mean a lot. Long things short, I reversed mosted of the api dll which connects to the PS3 and stuff and used it to encode some frames.

Rebooting and stuff works as well, the cecom running on the PS3 seems to be buggy though and doesn't reboot to game_os for me, not even with the original application. Attached source is more or less based on QT, and still a work in progress, just wanted to share it.

â€¢ corrected a bug in my yuv calculation
â€¢ removed IP address since it's not neccassarry, most likely it's just to specify an interface on which to listen
â€¢ put the sending and receiving in a thread
â€¢ added wrapper around the CodecSys functions
â€¢ added a basic commandline interface

I'm not sure but it might be easier to just get some open source encoder run on the PS3 with speed but I'm no good with PPC + SPU, at least not yet

From the ReadMe file: The IP is hardcoded as I just finished to reverse the api of the DLL so you have to change the corresponding string and length of the string.

For testing purpose I added an image which is converted to yuv420
and then added multiple times to the stream. No threading for now so you can only add a handful of frames until the buffer of the ps3 is full.

The resulting file will be raw h264.ES container which I added to a mp4 which mp4box to see what it looks like

cropping works if you stick to the right dimensions, that is a multiple of 16 in width and 4 in height. I just added it to rip some of my movies to put em on the ps3 so I didn't add the possibility to set it up via commandline arguments.

as for avisynth it shouldn't be to hard if you modify the frame_queue to support it and if it outputs as yuv42 as that is the format that is sent to the ps3, didn't take a look at avisynth api so I'm not sure.

as for motivation I simply forgot about it ;D well I might get some spare time mid next week so I might take a look.

i'll test your latest version to see whats changed. for now i see you added cropping, don't know if it's working also? how hard is it to let it support avisynth and let that do all the cropping, resizing, adding subtitles.

Ah, I see encode params called resizedWidth and resizedHeight. Hopefully setting these will do the trick!

yeah that's the way to go. you just have to care for the dimensions. I looked it up yesterday and the api checks if width is a multiple of 16 and height a multiple of 4 and gives a invalid parameters error otherwise.

just played around with the resizing a bit, the ps3 can do it for ya ;D only downsizing that is though.
I'll try how to use interlacing next and will mash up a version with variable encoding parameters next

Great that the PS3 can scale down! This would be primarily what I want to use it for, going from 1920x1080 down to 1280x720. Can you give me any tips about how to enable this now in the source code (before you release the next version?)

As far as the interlacing thing, I've looked into how to deinterlace content. Specifically, I've looked into detelecine, which reverses the progressive to interlaced process that happens when film is encoded for television. I think I might be able to implement this in your code; I'll let you know if I make progress.

cropping can be easily done in the function that generates the yuv frames as needed for the ps3, did this for my self, I could update the code later on, just have to clean it up a bit.

As for resizing you take a look at "CFrameQueue::getConverted()" it uses the ffmpeg function for resizing/scaleing etc. I just use it to convert the frame to yuv420, but the function can resize n stuff as well.

As for interlacing that can be done by the API somehow, didn't look into it by now, but basicly you set the corresponding encoder setting and double the keyframe interval and some other settings.

Reminds me Resolutions have to be multiple of 16 in width and multiple of 2 (not sure maybe 4) in height, gives a parameter_error otherwise.
